Attachment for pneumatic conveyers



Feb. 28, 1939. J. B. RASOR ATTACHMENT FOR PNEUMATIC CONVEYERS Filed Oct. 4, 1957 INVENTOR ATTO RNEYS Patented Feb. 28, 1939 UNITED STATES PATENT OFFICE ATTACHMENT FOR PNEUMATIC CONVEYERS 1 Claim.

The invention relates to a pneumatic gin feeder and more especially to an attachment for a pneumatic conveyer.

The primary object of the invention is the pro- 5 vision of an attachment of this character, wherein the same is effective for loosening cotton within a wagon for carriage by the pneumatic conveyor to the gin house or ginnery and in this manner eliminating hand loosening of the cotton 10 within the wagon or the like.

Another object of the invention is the provision of an attachment of this character, which is automatic in its working, being driven from an electric motor or other source of power and is susl5 ceptible of adjustment and separation from the conveyer when not necessary for use.

A further object of the invention is the provision of an attachment of this character, wherein the cotton within the wagon or other carrier 20 is loosened in an efficient manner and with rapidity and avoids or eliminates the difiiculty and in convenience of scratching or raking the cotton loose by hand.

A further object of the invention is the provi- 25 sion of an attachment of this character, which is simple in its construction, thoroughly reliable and efficient in operation, automatic in the working thereof, strong, durable, and inexpensive to manufacture and install.

30 With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the 35 preferred embodiment of the invention and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a vertical sectional view through a pneumatic conveyer and the attachment con- 40 structed in accordance with the invention.

Figure 2 is an end view thereof.

Figure 3 is a sectional view on the line 3-3 of Figure 1 looking in the direction of the arrows.

Similar reference characters indicate corre- 45 sponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally a pneumatic conveyer, only a portion thereof being shown, and B generally the 50 attachment constituting the present invention and hereinafter fully described.

This attachment comprises a two-part head involving the inner disk-like part 5 and the outer circular rim-like part 6, respectively, which 55 in the assembly constitute a gear casing, the parts exteriorly thereof being formed with bolt-receiving eyes I for bolts 8 carrying nuts 9 which fasten the parts 5 and 6 together.

The part 5 is formed with a center sleeve l slidably telescoped over the conveyer tube A. The conveyer tube A and the sleeve I0 have outstruck therefrom longitudinally disposed interfitted guide ribs l2 so that the attachment is free for sliding movement but is held against rotation on the conveyer A. 10

The part 6 accommodates therein a rotor i3 having a clearance II for the tube A and is provided with an internal annular retaining shoulder I4 for a raceway for bearing rollers [5 which are interposed between the rotor l3 and the said part B. This rotor l3 has formed therewith an internally toothed gear l6 meshing with a driving pinion ll, its power shaft 18 being journaled at IS in a bearing formed on the part 5. This power shaft I8 extends through a sleeve 20 20 and is operated from any suitable source of driving energy, for example, an electric motor (not shown).

Interposed between the part 5 and the rotor 13 concentric to the conveyer A are antifriction rollers 2| for minimizing friction in the operation of said rotor l3.

Formed on and projecting outwardly from the rotor I3 concentric to the conveyer tube A are saw teeth-like tines or prongs 22, which, on rotation of the rotor, function to loosen cotton within a wagon or other carrier so that it will be conveyed with rapidity through the conveyer tube A to a ginnery or gin house.

The sleeve B slides upon the conveyer tube A so as to recede thereon from the free end of the same when reaching close to the floor of the wagon or other carrier and in the working of the attachment the cotton within said wagon or carrier will be loosened so that such cotton will pass into the conveyer tube A for conveyance to the ginnery or gin house, suction action being had within the conveyer tube A in the usual wellknown manner and in such fashion hand pick ing or loosening of the cotton within the wagon or conveyer is avoided.

What is claimed is:

The combination with a pneumatic conveyer tube, of an attachment comprising a two-part head including an inner disk-like part and an outer circular rim-like part, respectively, means separably interfitting the parts with each other,

a central sleeve slidably telescoped over the conveyer tube and extending centrally from the disklike part, an internal annular shoulder formed on raceway for the said antifricti on means, power means having a gear meshing with the internally toothed gear of the rotor and concealed between the parts of said head, and prongs projecting from the rotor in an annular series con-' centric to the conveyer tube.
